My 2.5 year old cat is beyond fussy with food. I have tried just about everything the pet shop has to offer but she really is only enthusiastic about raw beef. I am reluctant to give her this too often but with all other types of food she just leaves it in the bowl and goes off in search of treats from other family members. I am really starting to worry that she isn't eating enough, although she seems very healthy. Anyone else had this issue?
